anyone out there running the cooper stt in the 33 to 35" range (285 - 315)...what tire pressure are you running in them? ive pretty much decided that me running 60# was too much, i think thats what the tire says is max pressure and I have a nasty habit of just airing them to the max and forgetting about it... i think thats why my tires have worn so bad, although i have gotten 40k out of them, but the wear pattern is terribly uneven with the centers being B-A-L-D...this makes me think i was way off in the air pressure dept... so what is everyone else running?

 

I'd suggest 40 psi.

 

44 lbs all around here.
